        We've made a mistake. I immediately ask the text QString image("data:image/png;base64,"); And so, pictures of the there is no. Need another code.

          qDebug() <<"image.isNull() :" << image.isNull()<<"screen->size() :"<<screen->size();
          return
          image.isNull() : false screen->size() : QSize(360, 640)

              Could the screen be incorrectly processed?

                    Hi
                    Not all android devices can take shot of QML. Need support in openGL driver.

                    Hmm. your Qt version seems new enough.
                    if you google "qt qml grabwindow bug" you can see there been quite some issues but
                    it should work with new Qt versions.

                    How type of android device are you using ? I mena is it old or kinda new ?

                        Well if possible you can try on another android device to see if same happens.

                            Does this code work on your phone? And if it works, what version of the code?
